My daughter had Fifth's at about
age 10 or 11. She had a rash and fever - but didn't feel too terribly bad. The doctor dx'd it and I think she may have been given an antibiotic, but I really can't remember. She recovered quickly and without complication. Nobody else in the family came down with it.
